Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18284, here are decompositions:
- 31 + 18253 = 18284
- 61 + 18223 = 18284
- 67 + 18217 = 18284
- 73 + 18211 = 18284
- 103 + 18181 = 18284
- 151 + 18133 = 18284
- 157 + 18127 = 18284
- 163 + 18121 = 18284
Showing the first eight; more decompositions exist.
